Guide to Access Junctions, Pipes, Anti-Flood Gullies and Back Traps

Important Parts of Commercial Drainage Systems

Drainage systems in industrial facilities require a set of dedicated features to deal with liquids effectively. Components such as access junctions, more info access pipes, anti-flood gullies and back traps help maintain reliability and long-term function.

Connecting Drainage Lines

Access junctions allow access for inspection while linking multiple pipes. Installed at convenient points, they help to find blockages and remove them quickly. In extensive drainage layouts, they streamline the effort needed for system upkeep.

Making Inspection Easier

Access pipes are upright pipes giving entry points into the network. Placed at regular intervals, they enable blockages to be cleared without costly excavation. They also double as overflow points, reducing the risk of wastewater overflowing inside commercial buildings.

Protecting Premises from Water

Anti-flood gullies protect surface water from overloading drains. Ideal in areas of frequent rainfall, they block backflow and maintain water moving into the system. This minimises potential damage, helps stop business downtime, and safeguards property and staff.

Stopping Backflow

Back traps provide a barrier that blocks wastewater moving in the wrong direction. Fitted at critical locations, they support hygiene, reduce odours, and avoid unsanitary conditions.
